Product details

168 MHz Cortex-M4 with 1 MB Flash — what this MCU delivers

It packs 1 MB of Flash and 192 KB of SRAM, giving firmware teams room for a full RTOS, communications stacks, and moderate data logging without external memory. The 51 GPIOs, combined with CAN, USB OTG, multiple SPI/I2C/UART interfaces, and a 12-bit ADC (16 channels) plus dual 12-bit DACs, let it handle mixed-signal control in a single chip.

Memory and peripheral fit

The 1 MB Flash is organized as 1M x 8; with 192 KB SRAM on die, the part can hold a moderate application image plus a FAT filesystem buffer or a TCP/IP stack without external SRAM.

Lifecycle status — active for new designs

ST lists this part with an active product status. It remains a valid choice for production builds and new design-ins without near-term obsolescence risk.

Frequently asked questions

Is STM32F405RGT6V obsolete or end-of-life?

No. The lifecycle status is active per STMicroelectronics. There is no EOL notice or last-time-buy schedule for this order code.

What is the maximum clock speed of STM32F405RGT6V?

The core processor runs at 168 MHz. That is the maximum rated speed for this part.

What is the difference between STM32F405RGT6V and STM32F405RGT6?

The suffix 'V' typically indicates a specific packaging or shipping variant (Tray in this listing) rather than a functional difference. Both share the same 168 MHz Cortex-M4 core, 1 MB Flash, 192 KB SRAM, and 64-LQFP package. The exact differences are in the ordering code — verify the specific variant against your BOM requirements.

Can STM32F405RGT6V replace STM32F405RGT6?

Yes, in most cases. The base product number is identical (STM32F405), and the core specs match. The 'V' suffix relates to the shipping medium (Tray). Confirm the specific variant's marking and any minor packaging differences with the datasheet before committing the BOM.
